Abstract
A system and method is provided that facilitates passive building information discovery. The system may include a processor configured to track positions in a building of portable devices over time and based thereon determine characteristics of the building including locations in the building where at least some of the portable device are unauthorized, based on communications received from radio-frequency (RF) sensors mounted in spaced-apart relation across the building. Such communications may include information detected by the RF sensors from RF signals from the portable devices that uniquely identify each portable device. The processor may be configured to determine when at least one of the portable devices is detected via a communication from at least one of the RF sensors at a determined unauthorized location in the building, and responsive thereto provide at least one notification that indicates that the at least one portable device was detected at the unauthorized location.
